This edited volume reviews our past and present understanding of the ecology of Australian freshwater fishes. It compares patterns and processes in Australia with those on other continents, discusses the local relevance of ecological models from the northern hemisphere and considers how best to manage our species and their habitats in the face of current and future threats. In view of these challenges, the need for redress is urgent.The chapters are written by some of our foremost researchers and managers, developing themes that underpin our knowledge of the ecology, conservation and management of fish and fish habitats. For each theme, the authors formulate a synthesis of what is known, consider the need for new perspectives and identify gaps and opportunities for research, monitoring and management. The themes have an Australian context but draw upon ideas and principles developed by fish biologists in other parts of the world.The science of freshwater fish ecology in Australia has grown rapidly from its roots in natural history and taxonomy. This book offers an introduction for students, researchers and managers, one that the authors hope will carry Australian fish biology and resource management to new levels of understanding.

Throughout much of the world, the common carp, Cyprinus carpio, is prized as an easily cultured, nutritious and tasty fish. It also features in a hugely popular fishery, especially in the UK, Europe and the USA. Koi, an ornamental type of carp, is revered by millions for its beautiful colours and intricate patterns. But despite carp’s popularity elsewhere, it is almost universally despised in Australia.Carp was originally introduced into Australia in the mid-1800s for ornament and angling, but since its escape into Gippsland and the Murray–Darling Basin, the fish has all but taken over inland waterways, wreaking ecological havoc in rivers, lakes and wetlands. In recent years, controversial methods, including a carp-killing virus, have been championed by some and maligned by others. Surprisingly perhaps, there still are carp enthusiasts in Australia, who fear what such a virus might do.Carp in Australia tells the story of how and why one of their most hated species was brought to the country. It explores carp’s relatively recent spread throughout Australia's largest inland river system, the Murray–Darling Basin, its impacts on freshwater ecosystems and the attempts to deal with the scourge. Readers are given key insights into the management challenges and possibilities in carp’s uncertain future in Australia. Is there hope for eradication, or is this fish here to stay?
